Recent Advisory News 2017 New York Fish Advisory The New York State Department of Environmental Conservation (NYSDEC) routinely monitors contaminant levels in fish and game. The New York State Department of Health (NYSDOH) issues advisories on eating sportfish and game taken in New York State because some of these foods contain levels of chemical contaminants that may be harmful to human health. The health advisories include general, specific, and regional advice on sportfish taken from waters in New York State, and advice on game harvested in New York State. The advisories are developed and updated regularly. For the most up-to- date and accurate data regarding fish consumption advisories, visit the NYSDOH's website, New York State Health Advice on Eating Fish You Catch. The 2017 advisory updates include changes for the Leatherstocking/Central, Adirondack, and St. Lawrence Valley regions: • In the Leatherstocking/Central Region, Mud Creek, a tributary to Sauquoit Creek, has been added to the list of waters with specific advisories. White sucker and brown trout have been added to the "do not eat" category in Mud Creek due to contamination from polychlorinated biphenyls (PCBs). White sucker has been added to the "do not eat" category in a portion of Sauquoit Creek also due to PCBs. Younger women (women under 50) and children under 15 should not eat any fish from waters with specific advisories. For more information about the Leatherstocking/Central Region Advisories, go to the Leatherstocking/Central Region Fish Advisory-webpage. • In the Adirondack Region, the length-based advisory of lake trout in Schroon Lake was updated, due to mercury contamination. For more information about the Adirondack Region Advisories, go to the Adirondack Region Fish Advisory webpage. • In the St. Lawrence Valley Region, an "eat up to one meal per month" advisory was issued for carp in a portion of the Black River, due to PCB contamination.

This newsletter provides a monthly summary of news about fish and shellfish ------- Fish and Shellfish Program newsletter July 2017 > Fish Consumption Advisory for Dan River, Virginia Metal Concentration in Fish Tissue-Implications for Public Health Following Coal Ash Release Abstract On February 2, 2014, approximately 39,000 tons of coal ash was released into the Dan River from a retired energy facility in Eden, North Carolina. A damaged storm water pipe beneath an ash basin reportedly caused the release. Coal ash is a gray, powdery material that is left over after coal is burned. Coal ash may contain metals such as arsenic, cadmium, chromium, mercury, and selenium. As part of a collaborative response to the event, the Virginia Department of Health (VDH) was responsible for identifying any public health risks associated with fish consumption following the coal ash spill, and they partnered with the Virginia Department of Environmental Quality (DEQ) to evaluate fish tissue data from the Dan River. In 2014 and 2015, Virginia DEQ collected fish samples along the Dan River to analyze them for 17 metals. To evaluate health implications of these metals, VDH determined acceptable concentrations in fish tissue using the U.S. Environmental Protection Agency's (EPA's) 2011 Exposure Factors Handbook, minimal risk levels, recommended dietary allowance, and adequate intake where appropriate. VDH determined that no additional fish consumption advisories were necessary for the Dan River but that the existing VDH fish consumption advisory for PCBs and mercury, which was in place prior to the coal ash release, should continue to be followed. Background The source of the Dan River is in Patrick County, Virginia and the river flows approximately 215 miles, crossing Virginia and North Carolina borders eight times, and ultimately forms the Kerr Reservoir in Mecklenburg, Virginia. The City of Danville and Town of South Boston are located on the Dan River and the river is the public drinking water source for both. The Dan River is also used frequently for recreational and agricultural activities. The coal ash release occurred in North Carolina approximately 25 miles southwest of Danville, and 70 miles from South Boston. The release prompted local residents to express concern regarding the impacts of coal ash on fish consumption, in addition to concerns related to public drinking water, agricultural use, and swimming. Methods and Results In 2014 and 2015, Virginia DEQ collected fish along the length of the Dan River, from the Virginia/North Carolina border to the Clarksville Marina. This was done to evaluate whether the coal ash release at Duke Energy in North Carolina has resulted in changes in heavy metal concentrations in fish tissue from the Dan River upstream of Danville. In both 2014 and 2015,160 fish samples were collected from 9 different sites along the Dan River and were analyzed for 17 different metal analytes including: aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium, copper, lead, manganese, nickel, selenium, silver, thallium, vanadium, zinc, and mercury. In all of the samples tested, aluminum, arsenic, barium, chromium, copper, manganese, mercury, selenium, silver, and zinc were detected at measurable levels. All samples (except for some mercury samples) in which the analytes were detected at measurable levels were below their respective VDH screening values. Therefore, these samples (with the exception of those mercury samples that were above its screening value of 0.5 parts per million [ppm]) are of no concern. 2 ------- Fish and Shellfish Program newsletter July 2017 Mercury was detected in all fish samples collected along the Dan River; however, most were below the VDH screening values. Concentrations of mercury exceeded the VDH screening value of 0.5 mg/kg (ppm) wet weight in fish collected in six of the sampling sites in 2014 and in two of the sampling sites in 2015, with tissue concentrations ranging from 0.51-1.25 ppm. The species with the highest mercury concentrations included largemouth bass, smallmouth bass, white bass, walleye, flathead catfish, and blue catfish. Conclusions and Recommendations Concentrations of metals analyzed in fish within weeks of the coal ash spill did not warrant a change to the existing fish consumption advisory for the Dan River. An increase in mercury concentration in fish occurred between 1999 and 2014. It is not known what caused the increase, but is not thought to be associated with the coal ash spill. In a letter dated March 9, 2017 to Virginia DEQ, VDH concluded that based on the 2014 and 2015 studies, the existing fish consumption advisory for the Dan River (see table below) is protective of human health.

The review concluded that the Hudson River cleanup is working as designed and, while not yet protective, is expected to accomplish its long-term goal of protection of human health and the environment when the cleanup is completed. In the interim, the state of New York has fishing restrictions and advisories in place to control human consumption of contaminated fish. Under the Superfund law, cleanups generally must be reviewed every five years after construction starts on a project to determine if they are working as intended and remain protective of human health and the environment. EPA's second five-year review is the culmination of an eleven-month evaluation process which included collecting new data, conducting an objective analysis of project activities, and a quantitative analysis of all available fish, water, and sediment data. The more than 1000-page report includes a detailed technical assessment and various technical data evaluations as appendices. The five-year review acknowledges that as many as eight or more years of post-dredging fish data may be needed to establish, with a high degree of confidence, a long-term statistical trend in levels of PCBs in the fish. The report is available at www.epa.gov/hudson. "EPA followed the requirements of the federal Superfund law and used the best available science to conduct this review," said former Acting Regional Administrator Catherine McCabe. "The question that the five-year review asks is 'do we still think the cleanup decision we made in 2002 will provide long-term protection of human health and the environment?' Based on the information and data that we have today, that answer is 'yes.'" EPA's two-part cleanup plan called for the targeted environmental dredging of PCB-contaminated sediment from a 40-mile stretch of the Upper Hudson River between Fort Edward and Troy, New York, followed by a period of monitored natural recovery. Dredging began in 2009 and was completed in 2015. It was one of the largest and most logistically complex environmental dredging projects ever undertaken in the United States, and resulted in the removal of about 2.75 million cubic yards of PCB-contaminated sediment. Approximately 310,000 pounds of PCBs were permanently removed from the river—twice the mass anticipated—representing an estimated 72 percent reduction in the overall mass of PCBs in the Upper Hudson River. The first five-year review for the site was conducted in 2012. This second five-year review considered all available data, including all fish, water, and sediment data collected over the past five years, but necessarily reflects only a single year of data about the post-dredging state of the river and fish. Because dredging was completed in 2015, the fish collected for sampling in both spring and fall 2016 were still affected by elevated PCBs levels during the dredging project. The data collected since the last five-year review show that the results are generally consistent with what EPA expected. The 2016 fish data suggest that the fish have begun to recover from dredging impacts and are generally back to pre-dredging levels. However, the 2016 data alone are not sufficient to evaluate post-dredging trends. 4 ------- Fish and Shellfish Program newsletter July 2017 "The early information that we have for sediment, water, and fish is encouraging. In the years ahead, we will collect more data to identify long-term trends," said former Acting Regional Administrator Catherine McCabe. "While the project was designed to set the river on a course for recovery, we have always explained that the recovery will take many years. It is not possible for the fish to fully recover immediately after the conclusion of dredging." As expected, average PCB concentrations in fish in the Upper Hudson are declining but have not yet reached protective levels. When EPA made its cleanup decision in 2002, they predicted that it would take years after dredging is completed for PCB levels in fish to reach levels where the existing fish consumption advisories may begin to be relaxed, and decades before fish can safely be eaten frequently. As a result, the fish consumption advisories are a necessary component of the site remedy. This is typical for Superfund sediment cleanup sites across the country. Since 1976, high levels of PCBs in fish have led New York State to close various recreational fisheries and to issue advisories restricting the consumption of fish caught in the Hudson River. As natural recovery of the river continues, human exposure to PCB-contaminated fish will continue to be controlled through fishing restrictions and fish consumption advisories issued by New York State. EPA set interim targets for the reduction of PCBs in fish tissue that would allow New York State to adjust the advisories and loosen the restrictions over time. The NYSDOH controls adjustments to the advisories. Hudson River-area residents who eat fish are encouraged to closely review and adhere to the advisories set by New York State. The five-year review includes a discussion of some of the efforts New York State has taken to improve the effectiveness of the advisories. EPA will continue to work closely with the NYSDEC and NYSDOH to improve their fish advisory outreach program. The sediment cleanup is now transitioning from the dredging phase of the project to a robust monitoring phase that will track the long-term recovery of the river over time to confirm that the cleanup is functioning as intended. This includes monitoring of sediment, fish, water, reconstructed habitats, and the caps that were placed in some of the areas of the river where PCBs remained. If EPA determines that the recovery is not occurring as expected, EPA will evaluate next steps. The next five-year review is expected to be completed in 2022. The next major component of the cleanup of the Hudson River PCBs Superfund site is now underway, and includes a comprehensive study of PCB contamination in low-lying areas of the Upper Hudson River that are subject to flooding, called the floodplains. Extensive soil sampling was conducted in 2016 and will continue in 2017. The five-year review report is available at www.epa.gov/hudson.

Other News Climate Patterns Influence Amount of Fecal Bacteria in Maryland Shellfish Harvest Waters National Oceanic and Atmospheric Administration's (NOAA's) National Centers for Coastal Ocean Science (NCCOS) scientists and their partners have identified a link between inter-annual patterns of precipitation and air temperature and fecal coliform levels in shellfish harvest waters in Maryland's portion of the Chesapeake Bay. Drawing on 34 years of monitoring data (1979-2013) from the Maryland Department of the Environment, the team found that fecal coliform tended to be higher in years when the bulk of precipitation occurred throughout the summer and fall. The study also revealed an intra-annual delay in timing between elevated precipitation and bacterial levels. Fecal coliform often peaked in late fall and winter, with precipitation peaking in summer and early fall. Additionally, continental-scale sea level pressure analysis showed an association between storm-generating atmospheric patterns and very high fecal coliform years. While natural resource managers have worked to reduce bacterial levels in the Chesapeake Bay, most rivers in the region contain areas where shellfish harvest is restricted due to excessive fecal bacteria. Understanding the links between these bacteria and climate variables will inform decisions about restricting access to shellfish harvest beds. The results of this study will also be useful for management of shellfish aquaculture, a growing industry in Maryland waters. This study was in done in collaboration with the Maryland Department of the Environment and the University of Maryland Center for Environmental Science, and was recently published in Water Research.

A new NOAA NCCOS-funded study recently published in Estuaries and Coasts explores how these changes are affecting fish and crustaceans in nearshore areas of the Chesapeake Bay. Across all species, small fish (<6o millimeters [mm], or 2.4 inches) were most abundant near wetlands and beaches, while large fish (>100 mm, or 3.9 inches) were most abundant at hardened shorelines. Shallow water can provide refuge from predators, making this habitat important to the survival of small fish, including juveniles of larger species. Very close to shore, water was deeper near hardened shorelines, which allowed larger fish to occupy these areas. Smaller fish either avoided deeper hardened shorelines, or were driven out or eaten by larger fish. In addition to harboring smaller fish, natural shorelines showed a greater variety of species, suggesting that shoreline hardening that comes at the expense of natural habitat likely reduces overall estuarine production.

Webinar Series: Introduction to Remote Sensing of Harmful Algal Blooms The National Aeronautics and Space Administration's (NASA's) Applied Remote Sensing Training Program (ARSET) will conduct a free, four-session online webinar series in September 2017 about remote sensing and harmful algal blooms (HABs). HABs can have a negative impact on the ecosystem and human health. Satellite remote sensing allows frequent data collection over a large area to identify impaired water quality from HABs. These data can inform decision-makers on where best to put their resources for taking water samples, determine what toxins are in the water, and inform decision-makers whether they need to change or move drinking water intakes and whether a fishery needs to be closed. Remote sensing data enable individuals and organizations to have more flexible plans for water sampling. The data can also be used to determine a more efficient and appropriate allocation of resources for protecting human health. The course agenda is available on the training webpage. Learning Objectives By the end of the training, attendees will be able to: • identify NASA's Earth Science remote sensing data products for the identification and monitoring of HABs; • describe how coupled remote sensing and modeling approaches are used in decision support tools; and • use a selection of NASA Earth Science data tools to monitor HABs. 7 ------- Fish and Shellfish Program newsletter July 2017 Intended Audience This training is intended for local, regional, state, federal, and international organizations interested in using satellite imagery for coastal and ocean applications.
